Reactions of used motor oil and residual oil using mesoporous MoAI₂O₃ catalyst

Abstract

In the present study, mesoporous Mo-based catalysts of different pore size ranges were synthesized and investigated for its hydrocracking activity. Catalyst pore size has been considered a property affecting the_mass transfer during reaction especially when dealing with large molecules such as residual oil. The effects of catalyst pore size on catalytic activities were evaluated via reaction conversion and liquid selectivity. Catalytic hydrocracking activity was also compared among the hydrocracking of used motor oil and residual oil. It was observed that the conversion is mainly related to the catalyst acid capacity, whilst the liquid products distribution in used motor oil is affected by calalyst pore size. Catalyst acid capacity promotes the crackrng activity.
